Abstract (en)

A matrix switching device includes a matrix board and a connecting pin. X-conductor patterns (24) are arranged in parallel with each other on one surface of the matrix board, and Y-conductor patterns (24-1) are arranged in parallel with each other on the other surface. Both the patterns are arranged in a matrix form. At each crossing point of the both patterns, a through hole (26) having conductive portions (25, 25 min ) respectively connected to the X- and Y-conductor patterns and an intermediate isolation portion for interrupting conduction between the conductive portions is formed in the matrix board. The connecting pin (27) includes conductive portions (28) respectively electrically connected to the X- and Y-conductor patterns through the conductive portions of the through hole upon insertion of the connecting pin into the through hole.
